THOMAS RODGERSON MARSDEN. OF OLDHAM, ENGLAND.

APPARATUS FOR FEEDlNG COTTON-OPENERS.

SPECIFICATION forming part of Letters Patent No. 789,378, dated May 9, 1905.

Application filed November 29, 1902. Serial No. 133,205.

To all whom, it may concern:

Be it known that l, THOMAS RODGERSON lVlARsDnN, a subject of the King of Great Britain and Ireland, manager in the employ of Messieurs Platt Bros. and Company, Limited, machinists. of Oldham. in the county of Lancaster, England, and a resident of Bank View, Derker, Oldham, aforesaid. have invented certain new and useful improvements in Apparatus for Feeding Cotton- Openers, (for which 1 have made application for patent in Great Britain, No. 16,364, dated July 24, 1902,) of which the following is a specilication.

This invention relates to improvements in apparatus for ineorporatii'ig or mixing cottonwaste and other fibrous material with the mass of fiber passing to or through opening or other preparatory machinery.

Considerable difliculty has always been experienced in the mixing and blowing rooms of cotton-mills in obtaininga thorough mixing or incorporation of the worked-up waste from the carding-engines and the like. This difficulty has become accentuated since the introduction and use of the hopper balebreakers and hopper-feeder, and especially in cases where the use of the mixing system has been abandoned.

In present practice two methods are generally used to mix the cotton-waste. In one case, where the system of mixing is employed, the waste is made up into a lap on a scutcher, and the lap of waste is put on the mixings, broken up, and thrown into the hopper-feeder along with the cotton. Where there are no mixings, the waste fiber is put through the hopper balebreaker by the attendant and there mixed with the mass of cotton under treatment. In this case the feeding of the waste fiber to the hopper bale-breaker is left entirely to the discretion of the operator, and it frequently happens that he will feed at one time considerably too much bulk of liber to compensate for previous neglect.

iln both the above cases the great drawback to success lies in'the fact that the waste fiber is introduced more or less in the mass. It is found that this mass of waste liber instead of being broken up and intimately incorporated with the main body of liber remains isolated and unmixed and retains this condition throughout all the process of preparing and spinning and causes defective and weak places in the yarn.

In carrying out my invention in connection with waste 1 treat the waste fiber so as to reduce it to an open and fleecy condition and incorporate it with the main body of liber while in such a favorable condition for being intimately mixed therewith.

The method of carrying my invention into effect is shown in the accon'lpanying drawings, in which--- Figure l is an elevation, and Fig. 2 an enlarged detail view. Figs. 3 and t are detail views of another part of the apparatus.

As shown in the drawings, I employ as a feed ing-machine a roving waste-opener A and feed the waste thereto on a creeper-lattice a. The cylinder Z) of the roving waste-opener reduces the waste to a very open and fleeeycondition. In conjunction with the roving wasteopener I employ a trunk or tube 0, connected With the exhaust-tubecZ of an exhaust-opener lap-machine B. The waste when reduced to an open and fleecy condition is drawn into the exhaust-opener B and there intimately mixed and incorporated with the main mass of fiber passing through the machine. The tube 0 is provided with a stop-valve 0 of any desired form.

The machine A for feeding the waste fiber is preferably provided with a suitable stopping and starting arrangement. which is shown in Fig. 2, and is connected with the opener B and lattice-feeder, so as to start and stop simultaneously therewith. This is effected as follows: In Figs. 1, 3, and 4t, f is the rod which is actuated on the completion of a lap to stop the 'leeding arrangements of the exhaust-opener lap B. I arrange that this red, through the medium of the bell-crank levers g ,r and connecting-rod 11 shall lower a pend ent rod 1'. Turning now to Fig. 2, this rod is connected to the pivoted weighted lever When the lever 7' is turned on its fulcrum 0, the finger Z: by means of a link vibrates the lever m and disengages the clutch half a, by means of which the feed-rollers of the roving waste-opener is driven. On the rod f is formed a ledge f, which is slipped through a slot: in thelever a. is connected a rod 1:, a spring 1* on which thrusts the rod 0; and rod f in the direction of the arrow, so as to thrust the ledge away from the slot t to form an abutment to prevent the withdrawal of the rod from the slot. As before stated, the rod f is connected by bell-cranks and a rod 76 to the rod 1:, the rod 2' to a loaded lever j, and when this lever falls the clutch mechanism is put out of gear; but so long as the lap is in course of formation this loaded lever 1' cannot fall. A spurwheel is rotated one revolution for each formation of lap, and on the completion of the lap an angular tooth 2/5 on a bracket w secured to the spur-wheel, comes into contact with a pin :13, carried on the end of the rod 0, and withdraws the rod '2; against the action of the spring #3. The movement of the rod c slides the rod f sufiiciently to remove the abutment or ledge f, and the rod i by reason of the load on the lever j pulls the rod f upward and causes the stoppage of the roving waste-opener. The movement of the rod 7, which passes through the ceiling to the feeding arrangements for the exhaust-opener lapmachine, is also utilized to stop and start such feed arrangements.

The feed-pipe c of the roving waste-opener may be connected to the exhaust-pipe (Z of the To the rod f lap-opener at any part of the circuit. Any suitable form of opener or machine such as, for instance, a Crighton opener lapmachine-- may be employed in lieu of the exhaustopener.

The actual mechanism employed does not form an essential part of my invention and may be varied by the use of various types of waste and exhaust openers.

Although I have particularly referred in my description to the treatment of cottonwaste, I do not confine myself to that alone, as my invention is applicable for mixing cotton or other fibers of different classes or for mixing fibers of different colors. My invention is also applicable for mixing spots or colored fibers with the main mass of cotton or other fiber under treatment intended for the production of spotted or variegated yarns.

I declare that what I claim is In combination for the indicated purposes, a roving waste-opener A, an opener lap-machine, a trunk connecting the waste-opener with the lap-machine and a stopping and starting connection between the said waste-opener and opener lap-machine.

In witness whereof I have hereunto set my hand in presence of two witnesses.
